The Reliable Model DDX Deluge Valve is a hydraulically op-erated, differential-type valve used to control the water supply to a deluge or preaction system. Deluge systems use open sprinklers or nozzles as discharge outlets in the fire area, while preaction systems use closed sprinklers or nozzles. Both sys-tems use separate detection devices to control the operation of the Deluge Valve. Three simple trim arrangements allow for actuation of the Reliable Model DDX Deluge Valve by utilizing manual, hydraulic, pneumatic, or electrical devices. These de-vices include break glass stations, wet pilot sprinklers, dry pilot sprinklers, thermal detectors, and smoke detectors.

The Reliable Model DDX Deluge Valve can be reset exter-nally, without cover removal. This is accomplished by pushing in and turning the external reset knob at the rear of the Deluge Valve (see Fig. 2).

Valve OperationThe Reliable Model DDX Deluge Valve is shown in both

closed and open positions in Fig. 3. In the closed position, the supply pressure acts on the underside of the clapper and also on the push rod through the push rod chamber’s inlet restriction. The resultant force due to the supply pressure acting on the push rod is multiplied by the mechanical advantage of the lever and is more than sufficient to hold the clapper closed against normal supply pressure surges.

When a fire is detected, a releasing device vents the push rod chamber to atmosphere through the chamber’s outlet. Since the pressure cannot be replenished through the inlet restriction as rapidly as it is vented, the push rod chamber pressure falls instantaneously. When the push rod chamber pressure ap-proaches approximately one-third of the supply pressure, the upward force of the supply pressure acting beneath the clapper overcomes the lever-applied force thereby opening the clap-per.

Once the clapper has opened, the lever acts as a latch, pre-venting the clapper from returning to the closed position. Water from the supply flows through the Deluge Valve into the system piping. Water also flows through the Deluge Valve’s alarm outlet to the alarm devices.

After system shutdown, resetting the Model DDX Deluge Valve is quite simple. Doing so only requires pushing in and turning the reset knob at the rear of the valve (see Fig.2). The external reset feature of the Model DDX Deluge Valve provides a means for simple, economical system testing, which is one es-sential facet of a good maintenance program. The external re-set feature does not, however, eliminate another important facet of good maintenance, namely, periodic cleaning and inspection of the internal valve parts.

In the event that water builds up inside the valve due to con-densate from the air supply system, or water left inside from valve system testing, a drain is available for venting. After clos-ing the main supply valve, a small valve over the drain cup can be opened slightly until the water inside the valve body and the main pipe column has drained.

Whenever ambient temperature conditions are high, the water temperature in the Model DDX Deluge Valve’s pushrod chamber could possibly increase, thereby increasing the pres-

sure in the chamber to values exceeding the rated pressure of the system. In an indoor installation where standard room tem-peratures are exceeded, a pressure relief kit may be needed. Pressure relief kit, P/N 6503050001, can be installed into the pushrod chamber’s releasing line to limit the pressure to 175 psi (12,1 bar).

Reliable Model DDX Deluge Valves with associated trim siz-es 2” (50 mm), 2½” (65mm), 3” (80mm) and 76mm, are rated for use at a minimum water supply pressure of 20 psi (1,4 bar) and a maximum water supply pressure of 250 psi (17,2 bar). Water supplied to the inlet of the valve and to the push rod chamber must be maintained between 40°F (4°C) and 140°F (60°C).Detection and Actuation

n general, the Reliable Model DDX Deluge Valve can be re-leased by any Reliable UL Listed or FM Approved device that opens sufficiently to vent the push rod chamber in response to a fire. The releasing device is simply connected to the push rod chamber’s outlet. When the releasing device operates and vents the push rod chamber, the Deluge Valve opens.

Typical releasing devices include hydraulic manual emer-gency stations, Model F1-FTR Fixed Temperature Detectors on wet pilot lines, dry pilot actuators, and solenoid valves. Model F1-FTR Detectors perform both Deluge Valve releasing and fire detection functions with wet pilot lines.

The use of a solenoid valve for Deluge Valve releasing en-ables various types of electrical fire detection devices to be used. Typical detection devices include electrical emergency pull stations, thermal detectors, and ionization or photoelectric smoke detectors. Electrical detection and releasing equipment used in Supertrol Electrical Systems is described in Bulletins 707 and 708, for both deluge and preaction systems

Fig. 3

The Wet Pilot Trim (see Fig. 4) is used when wet pilot sprin-klers or hydraulic manual emergency pull boxes are used for detection and releasing. This trim set provides a one and one quarter inch main drain, alarm test, supply pressure gauge, push rod chamber pressure gauge, push rod chamber supply connections, Model B Hydraulic Manual Emergency Station, and a connection for releasing devices.

The Dry Pilot Trim (see Fig. 5) is used when dry pilot sprinklers are used as the fire detection means. This trim set includes the Model LP Dry Pilot Line Actuator, air and water pressure gaug-es, low air pressure switch (for Dry Pilot Line), air pressure relief valve, connections for the air supply and pilot sprinkler lines, a one and one quarter inch main drain, alarm test, push rod chamber connections, push rod chamber pressure gauge, and the Model B Hydraulic Manual Emergency Station. Table A pro-vides the recommended air pressure when the dry pilot trim set is used as the actuation means.

The Electric Actuation Trim (see Fig. 6) is used when electric detection and releasing are desired. This trim set includes a solenoid valve (175 psi (12,1 bar) or 250 psi (17, 2 bar) rated), one and one quarter inch main drain, alarm test supply pres-sure gauge, push rod chamber supply connections, push rod chamber pressure gauge, and the Model B Hydraulic Manual Emergency Station. Detailed description of electrical operation can be found in Bulletins 707 and 708.

The Model B Hydraulic Manual Emergency Station is a standard item in all trim sets. However, the Model A Hydraulic Manual Emergency Station, described in Bulletin 506, is also available as an option.

All Model DDX Deluge Valves are listed by Underwriters Laboratories, Inc, and certified by UL for Canada (cULus) and certified by Factory Mutual Approvals, only when used with the valve manufacturer’s trim sets.
